IMPROVEMENT IN MACHINES FOR CUTTING B UNGS.

Specification forming part of Letters Patent N0. 44,267, dated September 13, 18(14.

My invention relates to an automatic contrivance forthe manufacture of tapered wooden bungs.

. Figure l is a perspective view of a machine embodying my improvements. Figs. 2 and-3 are, respectively, a vertical and a horizontal axial section through the cutter and its accessories. Figs. 4 and 5 are, respectively, a perspective view and an axial section of the cutter on an enlarged scale.

Ais the frame which supports the various operative parts. 'Ihe stuit is fed in along a guide-channel, B, between a pressureroller, C', and an intermittent feed-roller, C, operated by a` rotating cam, D, through the medium of a ratchet movement, E.

F is a sliding head-stock, in which is journaled the shaftG of the bit or cutter H, which consists of two flaring or conical serrated blades, I I', (corresponding to the desired dare of the bung,) whose interior surfaces serve to slick or burnish the sides of the bung in the very act of separation.

o J J' are two clamps, which, at the proper 1x1 tant, aie simultaneously advanced by the cams K K', so as to seize and hold the stuftl between them nhile the cutter operates upon it. The cutter H is rotated continuously by means ot' the belt L 1': om the drive-shaft O. The cutter headstock F being connected by a pitman, m, to a wrist, M, on the end otcan.- shaft N, is advanced at the proper moment to make a bung and again retracted, so as to leave the latter in thel grasp of the clamps J J', which now escaping from their cams and bein g retracted by the springs jj', the liberated bung then drops out of the machine, and, the feed-motion returning its action, the process is repeated, The motion of the cam-shaft N, I derive from a worm-movement, I", which is connected by bands Q and R with the same shaft C which drives the cutter.

I claim herein as new and of myinveution- I. The arrangement of guide-channel B, intermittent feed-rollers C C', rotating and sliding critter Il, and intermittent clamps J J', with their described or equivalent accessories, the whole being combined and op erating substantially as set forth.

2. While disclaiming the general principle of cutting bungs with a conical saw, I claim the construction of the conical cutter I I', with one or more slits or cutting-edges by which it is adapted to shave or slick the ptriphery ofthe bung in the act of cutting.

In testimony ot' which invention I hereunto set my hand.

FERD. ZUNKELER.
